WASHINGTON -- If you're an "American Idol" fan and didn't get enough of the popular show on TV, the top 13 Idol finalists are holding concerts across the country.

It's a grueling schedule that's testing the faith of some of the performers.

A Musical Roller Coaster

The touring Idols are halfway through a 46-performance concert tour that's taking them to more than 30 states.

"It's like a roller coaster ride without any seat belt on," Idol finalist Heejun Han told CBN News. "We just hold on to anything that we can to survive."

"It's fun, but I am so ready to be back in my own bed and get some good sweet tea and good southern home cooking," finalist Colton Dixon said.

He'll get it when the tour hits his home state of Tennessee next week.

Neither Dixon nor Han are shy about sharing their faith in Jesus Christ, and both said being on tour has tested them.

"Finding time to get in the Word is honestly like pulling teeth and I hate that," Dixon admitted. "You know, I never thought it would be like that, but it really is hard when you're out on the road."

Spiritual Battles

The music industry is glamorous, but Han said it's also "shady," leading to spiritual battles.

"When you are in the zone of this industry it attacks you so quickly that you didn't even know you had been attacked," he told CBN News.

"You look back and you think, 'Wow, I went too far and I became such a different person.' That's when you realize you have to go back to who you were," he said.

Dixon is working on a solo album that should be out before Christmas.

"I have a little over 30 songs now to pick for a record, so it's just about picking the right ones and running with them and seeing what God does with them," he said.

"My dream has been just a guy who is going after God's own heart," Han said.

For now, music is his ministry and social media his pulpit.

"I do believe myself as a pastor of that church. It's not a physical church," he explained. "But I have followers who will listen to me and I have people who see my messages."
